The PreciDrive technology redefines typical precision standards to +/- 10 seconds per year. The quartz crystal and integrated circuit (IC) are now sealed in a ceramic case, which protects them against moisture. The principle of thermo-compensation controls and regulates the motor pulses according to changes in the ambient temperature and means that PreciDrive meets the rigorous chronometer certification requirements of the COSC
(Contrôle Officiel Suisse des Chronomètres), provided the watch is not exposed to impacts and is kept at a temperature between 20° C and 30° C. This is a unique feat that brings real added value to the watch.
前驱器技术将典型的精度标准重新定义为每年+/- 10秒。石英晶体和集成电路（IC）现在被密封在一个陶瓷外壳中，以保护它们不受潮。热补偿原理根据环境温度的变化控制和调节电机脉冲，意味着预驱符合COSC严格的天文钟认证要求（控制瑞士天文钟），只要手表不暴露于冲击，温度保持在20°C和30°C之间。这是一个独特的壮举，为手表带来真正的附加价值。
